MC100EP40DTR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP40DTR2G is a three-state phase-frequency detector designed for phase-locked loop applications requiring minimal phase and frequency difference at lock. It operates with 3.3 V or 5 V power supplies, supporting PECL (VCC = 3.0 V to 5.5 V) and NECL (VEE = -3.0 V to -5.5 V) modes. The device features fully differential UP and DOWN outputs that provide pulse streams for VCO control when reference and feedback inputs are unequal. It includes an internal termination network for 50 Ω line impedance environments and a Phase Lock Detect pin indicating lock when the phase difference is 80 ps or less.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Maximum operating frequency exceeds 2 GHz typical
• Advanced high-band output swing of 400 mV with theoretical gain of 1.11
• Internal 50 Ω termination resistors for R and FB inputs
• Phase Lock Detect function activates at 80 ps or less phase difference

Clock Generators, PLLs, Frequency Synthesizers Applications

• Phase-locked loop circuits requiring minimum phase/frequency difference at lock
• High-speed clock distribution systems
• Frequency synthesis applications

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'R2G' corresponds to the Tape & Reel packaging containing 2500 units per reel. Confirm the TSSOP-20 package type matches the design requirements. Ensure the procurement source provides the official datasheet revision 15 dated February 2026 for accurate electrical characteristics and maximum ratings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for designs needing a PFD with reduced dead zone and high bandwidth. Verify input edge rates on Reference and Feedback pins remain below 5 ns for proper operation. Check thermal management needs as supply current can reach 170 mA at 85°C. Ensure external sinking supply of VCC-2 V is available for the VTX termination pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100EP series, which contains temperature-compensated devices. The DT suffix indicates the TSSOP-20 package. The DTR2G variant specifically denotes the tape and reel shipping format, differing from the tube-packaged MC100EP40DTG.
